Location: The Netherlands | Is there any chance the layout of the doors and fillomino puzzles can be changed? I think it would be handier to solve those with dashed line grids (like this: http://mellowmelon.wordpress.com/2012/02/01/puzzle-386/) or open line grids (like this: http://puzzleparasite.blogspot.nl/2011/12/puzzle-72-seethrough.html) instead of full line grids as in the instruction booklet. |

It is dashed in PB (similar to Palmer's link).

Location: Canada | I'm not sure I quite understand the rules of Water Fun. In the example puzzle, the bottom T-shaped tetromino and the L shaped-trimino have some of its cells shaded and some of its cells unshaded. |

I'm not sure I quite understand the rules of Water Fun. In the example puzzle, the bottom T-shaped tetromino and the L shaped-trimino have some of its cells shaded and some of its cells unshaded.
The words "Surface height" are key in the rules. The water can be at the bottom of a region, and not be at the top, but cannot be at the top while not at the bottom. Basic way to understand is, water flows downwards, so while you can have a shape filled from the bottom, you can't fill it from the top as the water will flow down anyway. |

Location: India | About the Penalty System :
I am not sure if this is the right penalty system. Isn't the whole intention of Instant Grading is to eradicate typos? A typo is a typo and should be penalized same for different puzzles. If a typo in Fence, penalty is .6 points, but for a typo in Number Snake, it is 2 points. So one has to be more careful entering the answer of high value puzzles. I am not sure if we want that side effect in Instant Grading.
Water Fun :
I think part of the problem is the way the image is drawn, and thats why ksun48 was not able to interpret. There are lots puzzle of this type at PuzzlePicnic. Here is the image redrawn in (close-to) PuzzlePicnic format.

True, but that's how it is in the system without instant grading.
I'm sure the merits and demerits will probably get some more discussion after the test, but I will say I am happy to see a penalty system that will actually make checking work worthwhile. |

Location: India | one doubt in Kakuro triplet.
Two cells on each side of a black cell will be considered as adjacent????
example 2nd white cell and 3rd white cell (seperated by a black cell having clue) in the IB....are they adjacent??? |

One Incorrect submission, and then a correct submission of that puzzle gives you 80% points of that puzzle. A correct submission after 2 incorrect gives 50%.
Interpret it that way :) |

Location: India | It can be a typo,or a guess,or a hurried entry with a bad answer format.So, this test uses a better instant grading system. |

Only that particular puzzle. |

Location: India | A bad answer format will not be penalized.
For example, "entering 3 digits while 4 digits are expected" will not be penalized. The individual submit button will not be enabled if the answer key is not formatted properly. |

Location: India | 3 things i need to be carefull is : (shared it thinking that it may be helpful to others too)
kakuro triplet - numbers repeat
doors - excluding cell itself
Hitori - shaded cells can be adjacent
2 questions ??
1) can one more sample of arithmetic box utilizing BODMAS Rule be uploaded (if possible)
2) Trimino hunt the triminos can be read from any direction right ??
i mean 223 can be read as 223 from left to right and 322 as if from right to left or 223 from top to bottom and 322 as if from bottom to top?? |

Yes, they can. In the given Trimino set in the IB, there is no 322 given, as 223 and 322 are considered the same instance(this is usually the case with domino hunt puzzles and it looks to be the same here). So hunt for the ones given without caring about direction and stuff.

233 is same as 332, irrespective of its direction, irrespective of it being horizontal/vertical.

The water cells do not 'have to' be connected. They may or may not be connected. |
